摘要/Abstract

摘要： 基于多跳中继的概念,研究了2种由多个用户组成的合作分集系统模型,即多跳和多路由合作分集系统。在瑞利衰落信道下,分别导出了这2种模型解码中继和放大中继的平均误码率和中断率。数值分析和仿真表明,多跳分集系统的性能随跳数的增加而下降,而多路由分集系统的性能随路由数的增多有较大改善;再生中继的性能在低信噪比时优于非再生中继,在高信噪比时两者的性能相似。

关键词: 用户合作分集, 多跳分集, 多路由分集

Abstract: Two models of cooperative diversity system composed of many users were studied based on multi-hop relaying concept, one of which was multi-hop system and the other was multi-route diversity system. Expressions for outage probability and average bit error rate (BER) of decoded relaying and amplified relaying systems were derived over Rayleigh fading channel, respectively. Numerical analysis shows the multi-hop diversity system is degraded as the number of hops increases, and simulation verifies that. On the other hand, the multi-route diversity system gets improved with the increasing of numbers of route. As a conclusion, the performance of decoded relaying is better than that of amplified relaying at lower average signal noise ratio (SNR). But at higher average SNR, there exists little difference between the two.

Key words: user cooperative diversity, multi-hop diversity, multi-route diversity
